Can someone provide me pictures or info how exactly must be the wires on each flipper coil?
Mine machine have many problems with wrong wires from the previous owner.

Thank you

So I have two problems with machine.

1.After correct position of the wires,the problem with the left not working flippers still persist-lower left and both upper playfield.
Also and all right lower flippers are active even in atract mode,I know this is not normal.

What I done:
-Checked all components on Aux board,and they are ok.
-Put new leaf cabinet switch and new EOS on flippers mecahnism,no change.

What think to do:
-Think to change K1 relay,I think these flippers are enable from it.Which are the transistors that control the flippers,if they are used,because in the manual is not show.
-Try with another AUX board
Any other suggestions?

2.The three pop bumpers and both slingshots locks immediately after power on(all special solenoids)

What I done:
-There have several bad transistors and they were changed with new-still same effect.I begin to think it's a PIA,because I already changed their ICs before PIA

3.There also have some thing that disturb me with MPU board
-All ICs on MPU board have some type of short,what do I mean:
When I try to test some 7402 or 7404 or 7406(I made this many times on other boards),and put Red probe of DMM on pin 7 and Black on pin 14,there have continues buzz and show .044,not full short,but if it's ok,It must beep one time when I touch these two pins.
I compared this with F-14 board that I have and working,and it's beep one time like it must be.
Also when continued to test U56(7406),it have connection between pin7 and pin6(full .001 with DMM),which is not normal too.If I can remember pin6 goes to Vcc on U54(PIA).Once again I compared with F-14,and it's not like that.
And tested all Vcc from ICs to GND,there have connection.
So there have something with this MPU board,but the game runs,motor is testing normal,you can start new game and lamp and switches are all working.

What I done:
-Tested these with the board connected with all wires,and on the bench without them.
-Tested also with removed battery holder.

Sorry for the long post,but I want to be precise

Update:
-checked the voltages and all coils have 70v
-ground each coil and all of them are working
-ground Q8 and can hear that only the relay on AUX driver board to "click",but not the one on CPU boars

I think now to replace K1 relay on CPU board

Any other sugestions?

Update:
-tested the original K1 relay outside the board,and it clicks and all contacts are good.Also tested the diod and the transistor that controls is-all good.So the problem is not the relay.
-tested Q7 and Q8 on CPU board-ok

But the machine don't want to click it.
